Single-Screw Extrusion Geo-membrane Suppliers and Manufacturers

Single-Screw Extrusion Geo-membrane Supplier Concentration and Factory Types

Suppliers of Single-Screw Extrusion Geo-membrane equipment in the observed results are concentrated in China, with Shandong and Shanghai both represented as supplier locations. Shandong stands out in the current results, with suppliers based there listing geomembrane extrusion lines among their main products alongside related plastic machinery such as pipe making machines, plastic extruders, HDPE and PVC pipe machines, and drip pipe extruders. A Shanghai-based supplier also appears, covering sheet extrusion lines and related plastic extrusion equipment. This clustering suggests that buyers searching this category will encounter a mix of suppliers from established plastics machinery regions, but location alone should not be treated as proof of capability.

The observed company types are predominantly Manufacturer/Factory, with at least one supplier labeled as a combined Trading Company and Manufacturer/Factory. A manufacturer listing typically indicates direct production control over the extrusion line, while a hybrid or trading entity may broker machines from partner factories. Main product ranges also differentiate suppliers: some specialize in geomembrane, sheet, and pipe extrusion lines, while others list broader portfolios including PP PC hollow sheet lines, PC sunshine roofing panels, and PP PE foam board extrusion lines. Suppliers with a tighter focus on geomembrane and sheet extrusion equipment may offer deeper model-specific experience, whereas broad-line suppliers may offer one-stop machinery sourcing. Buyers should confirm which entity will actually build, assemble, and test the line before assuming factory-direct control.

How to Verify Single-Screw Extrusion Geo-membrane Suppliers

Verification should begin with the platform-displayed attributes visible in the results. Several suppliers in this category carry ISO 9001 system certification, and at least one is verified through BV (Bureau Veritas), a third-party onsite verification route. Treat these as starting signals rather than final proof: a BV verification badge generally indicates an onsite check was performed, but buyers should ask what the verification covered, such as factory premises, production processes, or trade operations. For any certification displayed on a product, such as CE or ISO 9001 markings that appear in the observed product attributes, request the actual certificate documents and check the certificate holder's legal name against the supplier's business license.

Beyond displayed credentials, buyers should verify that the supplier actually manufactures the specific line type. Observed product evidence includes named models such as the KT-SJ150 and production lines labeled Geomembrane production line 329, 330, and 100, along with stated production experience of 16 years from one supplier. Ask for references or case records for the exact model range, and confirm whether the supplier holds its own brand; one observed supplier lists its own brand, Kruto, which suggests in-house design rather than pure resale. Video calls showing the assembly floor, a live or recorded machine trial using PE or HDPE resin, and a factory audit report are practical confirmation steps. Never rely on a single badge; cross-check location, company type, and product evidence so all displayed claims tell a consistent story.

What to Compare Across Single-Screw Extrusion Geo-membrane Suppliers

Compare suppliers on the dimensions that actually appear in the results rather than assuming every supplier publishes the same data. Lead time is one useful field: an observed supplier quotes 45 days, but this figure is specific to that supplier and may vary with line size, season, and customization level, so ask each candidate to confirm lead time for the exact configuration. MOQ is another: observed MOQs in this category are as low as 1, which is typical for capital machinery sold as a complete line rather than bulk goods, but confirm what one unit includes in terms of dies, screen changers, and auxiliary equipment.

Technical comparison should draw on the product attributes that suppliers actually publish. Observed specifications include sheet widths of 2000–8500mm, thicknesses from 0.3–4mm depending on the model, capacities of 400–1200kg/h, single-screw extrusion, cloth-hanger T dies, plate-type double-station hydraulic screen changers, and melt metering pumps with pressure stabilization. Component branding also differentiates suppliers: observed lines list Siemens motors and PLCs, ABB inverters, NSK bearings, and specific die and screen-changer brands. Automation level, computerized control, and customization availability are shown as attributes for several listings. Also compare main products and company type, since a Manufacturer/Factory focused on geomembrane and sheet extrusion may respond differently than a broad trading entity. Response speed is not always displayed; if no response-time figure is shown, test it directly with a technical inquiry and record how quickly, and how substantively, each supplier replies.

Common Single-Screw Extrusion Geo-membrane Sourcing Risks

The most common risk in this category is specification ambiguity. Observed listings span wide ranges, such as sheet widths of 2000–8500mm and thickness ranges that differ between models, so a supplier quoting a "geomembrane line" without pinning down width, thickness, resin type (PE, HDPE, LDPE, LLDPE are observed raw materials), and target capacity may deliver a configuration that cannot run your intended film. Another risk is the manufacturer-versus-trader gap: because at least one supplier is labeled as a combined Trading Company and Manufacturer/Factory, buyers may believe they are dealing with the factory when a partner actually builds the line, which complicates warranty claims and spare-parts supply.

Certification risk is also real. Product listings display certifications such as CE and ISO 9001, and some attribute strings combine multiple marks, so buyers should verify each certificate's scope, validity, and issuing body rather than accepting concatenated labels at face value. Brand-name component risk is subtler: listings cite Siemens, ABB, NSK, and other brands, but you should require the supplier to state in the contract which components are genuine, which are "or as required," and what substitutes are permitted. Pricing spreads are wide in the observed data, with minimum prices ranging from 20,000 to 100,000 USD-level figures and maximums reaching 500,000–600,000 USD-level figures, so an unusually low quote may reflect a stripped-down configuration. Finally, packaging is listed only generically, such as standard packing or wooden cases, so clarify export-grade protection for heavy extrusion components before shipment.

Single-Screw Extrusion Geo-membrane Regional Sourcing and Logistics

The observed supplier locations are China Shandong and China Shanghai, which means most logistics planning in this category involves Chinese export routes. Shandong suppliers appear frequently in the current results, and at least one product lists Qingdao, Shandong, China as the production origin, which is relevant because Qingdao is a major container and heavy-cargo port serving Shandong's industrial base. Shanghai-based suppliers likewise sit near one of the world's busiest container ports. Because these are heavy industrial lines, freight planning should account for equipment dimensions: one observed listing specifies a line footprint of 25m x 10m x 3m, which typically means disassembled shipment in multiple wooden cases or on wooden pallets, consistent with the packing methods listed in the results.

When identifying clusters without displayed location data, buyers should triangulate: check the supplier's registered address, the product origin field, and port of loading mentioned in quotes. For logistics, request a detailed packing list showing case counts, weights, and dimensions per package, since crane handling and container or flat-rack selection depend on it. Confirm whether installation supervision, commissioning, and operator training are included and whether the engineers travel from the Shandong or Shanghai site. Lead time interacts with logistics: with an observed lead time of 45 days from one supplier, add ocean transit and customs clearance on top, and clarify Incoterms so responsibility for inland haulage, port charges, and insurance is unambiguous before the machine leaves the factory.

Single-Screw Extrusion Geo-membrane Commercial Terms and Order Planning

Commercial terms in this category should be planned around capital-equipment realities. Observed price ranges span roughly from 20,000 to 600,000 USD-level figures depending on the model and configuration, and observed MOQs are 1, reflecting single-line purchases. Because customization is listed as available on several lines, expect quotations to vary with width, thickness range, capacity, and component brands; require an itemized quotation separating the extruder, die head, screen changer, calendering and winding units, electrical controls, and optional equipment such as multi-group mixers or melt metering pumps. Confirm payment structure separately, as payment terms are not displayed in the results; typical capital-machinery practice involves staged payments tied to milestones, but you must agree terms directly with each supplier.

Order planning should anchor on the line's model and origin details that suppliers publish, such as model numbers KT-SJ150, SJ150/36, or Lmsb120/33 and Lmsb150/33, plus the stated origin. Put the agreed technical attributes into the contract: sheet width, thickness range, capacity in kg/h, screw type, listed component brands, certification requirements, packing method, and a stated lead time, with the 45-day figure from the observed data serving only as a benchmark to compare against each supplier's own confirmation. If a marketplace offers escrow or trade assurance, verify whether it applies to this supplier and transaction, since escrow coverage is not shown for every listing. Finally, plan acceptance testing: define trial resin, output targets, and film quality criteria before final payment, so performance disputes have contractual grounds.
